Ok so my problem is that on line 49 the a = reader.net().charAt(); line I get an error saying 'Method charAt in class String cannot be applied to given types;
a = reader.net.().charAt();
^
required: int
found: no arguments
reason: actual and formal argument lists differ in length
1 error

So what I am asking is what I can do to fix this? Also on a side question On the line where I put 'System.out.println( "Payroll cannot be a negative number" );, how can i get my program to stop there? Like just exit the program, at the moment it just keeps repeating the phrase.
